模糊PID玉米免耕机排种施肥控制方法研究
Study on Control Method of Seed Metering and Fertilization for Corn No-tillage Seeder
摘要
Abstract
In order to achieving precise control of sowing amount and fertilization amount for no-tillage seeder,this sys-tem was designed based on fuzzy PID control.Firstly,seed output model was found,while the seed metering shaft speed was taken as control parameter.Secondly,control model of fertilization amount was found,after effects of rotation speed of fertilizer discharge shaft,length of fertilizer discharge shaft and speed of no-tillage seeder on the fertilizer error,and then,rotation speed of fertilizer discharge shaft was taken as control parameter.Speed regulation of drive motor was achieved based on fuzzy PID control,and then,the rotation speed of fertilizer discharge shaft and seed discharge shaft were controlled to adjust sowing amount and fertilization amount.The system tests were taken,response time is 0.8 s,as motor speed adjusted from 0 to 50 r/min.Coefficient of variation for fertilization ranged was[2.6,4.1].关键词
